In preparation for their struggle against Kang and the Avengers Unity Division, the Apocalypse Twins recruited four new Horsemen in defiance of the Celestial protocols and to psychologically manipulate this specific team of Avengers. Four Celestial Lifeseeds were used to resurrect these fallen souls, who were then exposed to Celestial Deathseeds to further corrupt and empower them. In addition to the fallen X-Man Banshee and Wolverine's late son Daken, they resurrected Wonder Man's brother the Grim Reaper and the fallen Avengers, Sentry.
